Extended Data Fig. 8: Theoretical simulation for the band structures and Fermi surfaces of Mn3Pt under different spin configurations.
From: Room-temperature magnetoresistance in an all-antiferromagnetic tunnel junction
a, Atomic and simulated spin configurations of Mn3Pt under positive and negative saturation magnetic fields. b, Corresponding band structures and spin expectation values <σx>, <σy> and <σz> for Mn3Pt. The colour scale for the spin values is shown on the right. c, Three typical Fermi surfaces and spin expectation values with spin configurations of bulk Mn3Pt under positive saturation magnetic field. The colour scale indicates the magnitude of spin. All the first-principles calculations were conducted in the absence of magnetic field, and only the spin configurations under positive and negative saturation magnetic fields were considered.
